UML22 — inability to specify ordering of messages connected to gates is problematic

Open Closed All
  • Key: UML22-363
  • Legacy Issue Number: 12167
  • Status: closed  
  • Source: International Business Machines ( James Bruck)
  • Summary:

    In the 2.1.1 specification (070205):

    Gates are simply MessageEnds and not some form of OccurrenceSpecification. This makes relative ordering of messages between gates on different InteractionUse within an interaction impossible.
    In addition to gates on InteractionUse, gates on Interaction that have outgoing messages cannot specify any relative ordering.

    The inability to specify ordering of messages connected to gates is problematic.

  • Disposition: Resolved — UML 2.2
  • Disposition Summary:

    Add clarification that Gates are messageEnds which are ordered by the occurrences at the opposite ends of
    the two messages linked by the gate. UML 2.5 already added several clarification on semantics of Gates.
